Global scene. Globally a cement major such as Italcementi consumes annually some 6000GWh of power and 35,500,000Gcal of heat for a total of 5Mtpe. This is the same total energy as consumed by approximately 1.6m Italians or 0.6m Americans per year.

Coal prices in China went on a roller coaster ride last year, with a major trough at the start of the year as the Covid-19 pandemic brought economy activity in the first quarter to a near standstill. As prices sagged to 495 yuan per …

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal ...

Electric cars had a record year in 2020, with Europe overtaking China as the biggest market. After a decade of rapid growth, in 2020 the global electric car stock hit the 10 million mark, a 43% increase over 2019. Battery electric vehicles (BEVs) accounted for two-thirds of new electric car registrations and two-thirds of the stock in 2020.

The energy problem that receives most attention is the link between energy access and greenhouse gas emissions. But the world has another global energy problem that is just as big: hundreds of millions of people lack access to sufficient energy entirely, with terrible consequences to themselves and the environment.

Energy is the ability to do work. Scientists define energy as the ability to do work. Modern civilization is possible because people have learned how to change energy from one form to another and then use it to do work. People use energy to walk and bicycle, to move cars along roads and boats through water, to cook food on stoves, to make ice ...

1. Carbon-Based Fuels Dominate Global Energy Use. Crude oil, coal, and natural gas supply about 85% of the energy used in the world. Fossil fuels are valuable as sources of energy because they contain hydrocarbons and other carbon-based materials. Hydrocarbons are any of a class of organic compounds composed only of carbon and hydrogen.

Raw materials Steel production. Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.

In our International Energy Outlook 2021 (IEO2021) Reference case, we project that, absent significant changes in policy or technology, global energy consumption will increase nearly 50% over the next 30 years. Although petroleum and other liquid fuels will remain the world's largest energy source in 2050, renewable energy sources, which include solar and …
